Working with Dolly is a great rush for me because we are good friends, and we have been, forever. We just flirted a lot. I can't explain it, but flirting is more electric than passion. It's the anticipation. She does it better than anybody I've ever seen, and it's just good fun.

We did some massive flirting in front of the nation, but there was never anything more than that.

I love to hear a choir. I love the humanity... to see the faces of real people devoting themselves to a piece of music. I like the teamwork. It makes me feel optimistic about the human race when I see them cooperating like that.

People may think that it's 'uncool' to work with the biggest producer in the world-I don't give a fuck.

I started to write the song. And I was in Gladewater, Texas, one night with Carl Perkins and I said, I've got a good idea for a song. And I sang him the first verse that I had written, and I said it's called "Because You're Mine." And he said, "I Walk The Line" is a better title, so I changed it to "I Walk The Line."

I think the best duets are those where there's a dialogue back and forth, and then the two singers go into a thing together.
